Parse.com provides back-end support for your mobile application.You have already used openfire as back-end so you can not login to parse.com as a user which was created in your server.
There is a way that you can register user at both parse and openfire. But it might cause some issues.It may not sync or you need to sync the data like user contacts,chat history etc. manually.For more do your own research.I don't know much about parse. Hope it will help.
